  13. Mechanical Energy • Moving objects • Sound

  14. Radiant or Light Energy • Most are invisible • UV rays, X-rays, radio waves

  15. Thermal Energy • Energy of moving or vibrating molecules • The faster they move the hotter they become

  16. Elastic Energy • A stretched rubber band, compressed spring or jack-in-the-box
